Niehaus said questions remain over whether a statewide ban can be enforced. He says it would be difficult for authorities to tell the difference between when drivers are texting versus when they are manually making phone calls.

The GOP-controlled House passed the bill in June. It would make writing, reading and sending text messages while driving a minor misdemeanor with possible fines of up to $150 dollars.

At least 30 states and the District of Columbia ban texting for all drivers.
